I built a 3 axis CNC milling machine. To run it I use a PC and mesa 7i76eu. They work well but every now and then I get an following error. To minimize this I increased latency from 1000000 to 1500000. Following errors are now less common (sey aonce per two hours of running). It is not critical but still it is anoying to rehome the machine. Is there anything I can do to optimize the computer and mesa comunication so there will not be any following errors.
Changing the PC would be my first choice as i can find used ones cheap, the "Enterprise edition" Dell or HP or Lenovo or Fujitsu have worked nicely for me, and so have some laptops like Lenovo T470, X1 yoga, Y370, but these are not guarantied to always work.
For now you can try isolating CPU's as plenty of members here had good results with it and it's easy to do
